QUALITY ASSURANCE/ MACHINE BREAK IN
The SPE Floor Grinder is the product of extensive engineering development designed to
give long life and unmatched performance. The Floor Grinders are shipped completely
assembled.
You can help ensure that your Floor Grinder will perform at top levels by observing a
simple routing on first use. Consider that your new Grinder is like a new car. Just as you would
break in a new car to the road or any new machine to the job, you should start gradually and
build up to full use. Learn what your machine can do and how it will respond. Full throttle and
control may be used after this time period, as allowed by material. This will serve to further
break in the machine on your specific application, as well as provide you with additional
practice using the machine.
We thank you for the confidence you have placed in us by purchasing a SPE Floor
Grinder and wish you many years of satisfied use.

ROUTINE SERVICE INTERVALS
Due to the nature and environment of use, Floor Grinders could be exposed to severe
operating conditions. Some general maintenance guidelines will extend the useful life of your
machine.
• The initial service for your grinder should be performed after 25 hours of use, at which time
your mechanic (or authorized repair shop) should complete all the recommended checks in the
schedule above. The maintenance log is handy for keeping a record of the maintenance
performed and the parts used for servicing your grinder.
• Regular service according to the schedule above will prolong the life of the floor grinder and
prevent expensive repairs.
• Keeping your floor grinder clean and free from debris is the single most important regular
maintenance operation, over and above the checks in the service schedule above, that can be
performed. After each use your grinder should be cleaned to remove any dust and debris from
the undercarriage and surrounding components.
• In the Service Schedule above, items that should be checked, replaced or adjusted are
indicated by “o” in the appropriate column. For ease of recording place, a checkmark through
the “o” when the item is complete. If an item is not required or not completed place an “x”
through the “o” in the box.
• Failure to have your floor grinder regularly serviced and properly maintained in accordance
with the manufacturer’s instructions will lead to premature failure and void the warranty.

OPERATING SAFETY PRECAUTIONS
The floor grinders are constructed according to existing safety rules and regulations.
These technical precautions should not be removed or changed under any circumstances.
While operating the machines the following points should also be kept in mind:
The instructions provided in this manual are done so to ensure the operator’s safety as well
as that of others, the equipment, and the job site. Failure to follow these guidelines can lead to
serious personal injury and even death. The operator and any service personnel should read
and understand the entire manual before working with or servicing any SPE Floor Grinder.
•The grinders should always be operated with all safety covers and technical precautions.
•During transport, cleaning, repair or maintenance the grinder must be disconnected from
the power supply. That also applies to the changing of tools.
•The safety ring can only be removed while operating the machine directly against the
wall. While operating the machine without the safety ring dust can be generated. In this
case the operator must wear a mask. In all other cases the grinder must be operated
with the safety ring.
•The operator should never leave the machine unattended during operation.
•Before leaving the machine, all rotary parts should be brought to a standstill. Electric
models must be disconnected from the power supply. Make sure that the machine cannot
roll or move by itself.
•After any maintenance and adjustment all safety covers must be reattached.
•Ear protectors must be worn.
•Eye protectors must be worn.
•Safety shoes with steel caps must be worn.
•In the event of a large amount of dust during operation, connect a dust collector to the
grinder.
•Depending on the floor (floor coating) grinding can produce gases. The operator must be
held responsible if these generated gases are dangerous and if protection is necessary.
Grinding floors containing asbestos is especially dangerous and can cause health
problems. Special masks must be worn which keep the breathing airclean. A dust collector
must be used and should be equipped with filters suitable for asbestos dust.
•The floor must be brushed before grinding because loose material could get into the tools
and fly away. Anchor screws and bolts coming out of the floor can also be seen better if
the floor is clean. If the grinding head hits a anchor screw or bolt then serious damage can
be caused to the machine or grinding head.

OPERATION INSTRUCTIONS
SETTING UP YOUR FLOOR GRINDER
Your Floor Grinder comes fully assembled with handle and motor fully installed. The
handle is folded to allow for easier transportation. The handle can be moved into operating
position by releasing the two locking pins on either side of the handle, the handle can then be
moved into 1 of 3 positions. With the handle in the desired position the locking pins can be
reengaged. Tooling can now be installed, and your Floor Grinder is ready for use.
PRIOR TO OPERATION
•Make sure that all dust, debris etc., are thoroughly removed from the unit prior to
operation. Special effort should be given to the bottom of the machine where the tooling
plate is located.
•Check all bolts and screws for tightness and make sure all bolts and screws are securely
tightened. Loose bolts and screws may cause damage to the unit. Make sure tooling is
properly installed.
•Connect the vacuum hose to the dust extraction port if a dust control vacuum is being
used.
•Ensure the power supply is correct for the machine before making the connection.
CHANGING OR INSTALLING TOOLING
•Tilt the machine onto the back wheels and rest it on the handlebar.
•All tooling is fixed in grooves and held in place by magnets.
•Check the grinding tool for wear and replace if needed.
•Remove tooling by sliding tooling to the centre of the disk.
•Fix new tools by sliding the tool in the groove starting from the centre of the machine
ATTENTION: Before working on the grinder bring the motor to a total stand still and
disconnect from the power supply.
CAUTION: Tools can be hot after use.

OPERATION
Operating
After mounting the appropriate tools and plugging the machine in to the correct power source
the operation of the grinder can begin.
Check that the stop button is out by rotating clockwise. Lift the grinding head slightly by tipping
the machine back, then press the start button. Lower the head back onto the floor, and ensure
the head moves evenly across the surface for a smooth finish.
•The machine is also fitted with two removable panels in the dust shroud which can assist
with edge work. Undo the two thumb nuts and remove the panel to allow the grinding head
to get closer to the vertical surface. Once done, replace the panel then refit and tighten the
two thumb nuts. (Turn off machine first before removing the panel)
Stopping procedure
To stop the machine, press the red stop button and allow grinding head to slow to a stop on the
floor. Unplug machine if job is finished and when changing tools or performing work.
ATTENTION: When switching on the motor, the machine may jump slightly due to
rotating tooling.
ATTENTION: Never switch on machine while the grinding head is on the floor.

ELECTRICAL INSTRUCTIONS
The DFG280 machine is supplied with a specially commissioned 110V electric motor and
starter switch assembly. Each unit is fully tested, and the safety overload relays have been
calibrated and set according to the manufacturer’s specifications. In the event of the
malfunction on a new machine the owner should first check that the power supply on-site is
suitable and adequate.
DFG280-6 (120V)
•The 120V motor requires a 15 Amp supply.
All cables should be fully uncoiled and never left wrapped around cable reels or tied in loops.
The motor is protected with a safety trip in the panel. Should the trip be activated, it will reset
automatically after cooling down. Damage will occur if the motor repeatedly cuts out. Possible
causes are either an inadequate power supply, overloading of the machine, or an electrical
fault.
